PS9552L3-V-E3-AX Equivalent & Substitute Parts

Part Overview

The PS9552L3-V-E3-AX is a 2.5A Gate Driver Optical Coupling device rated for 5000Vrms isolation with single-channel operation in an 8-SMD Gull Wing package. This component belongs to the NEPOC series and is currently classified as Obsolete. Due to its discontinued status, equivalent substitute parts must be identified to maintain design continuity and enable procurement for legacy system maintenance and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS9552L3-V-E3-AX is determined by equivalence across the following critical electrical and mechanical parameters:

• Isolation Voltage: 5000Vrms (mandatory match)
• Number of Channels: 1 (mandatory match)
• Peak Output Current: 2.5A (mandatory match)
• Propagation Delay: 500ns max for both tpLH and tpHL (mandatory match)
• Common Mode Transient Immunity: 25kV/µs minimum (mandatory match)
• Output Supply Voltage Range: 15V ~ 30V (mandatory match)
• Operating Temperature Range: -40°C ~ 100°C (mandatory match)

The HCNW3120-500E from Broadcom Limited qualifies as a direct functional equivalent based on electrical parameter compliance across all critical specifications. Both devices employ optical coupling technology for galvanic isolation in single-channel gate driver applications.

Parameter Comparison

Engineering Selection Recommendations

The HCNW3120-500E is appropriate for direct substitution of the obsolete PS9552L3-V-E3-AX in applications requiring optical gate driver functionality at 5000Vrms isolation with 2.5A peak output current.

The Broadcom HCNW3120-500E maintains Active product status with current manufacturing availability, ensuring long-term supply chain continuity compared to the discontinued PS9552L3-V-E3-AX. Both devices hold equivalent regulatory approvals from UL and CSA. The HCNW3120-500E holds ROHS3 compliance certification.

The primary mechanical difference exists in package designation: the original device specifies 8-SMD Gull Wing format, while the substitute uses 8-DIP Gull Wing format. This distinction affects board layout and assembly methodology but does not alter electrical compatibility when proper footprint adaptation is implemented.

Frequently Asked Questions (FAQ)

Q: Can the HCNW3120-500E directly replace the PS9552L3-V-E3-AX without circuit modifications?

A: Electrical substitution is direct based on parameter equivalence. However, the package format difference (8-SMD versus 8-DIP Gull Wing) requires PCB footprint modification and assembly process adjustment. The pinout and functional behavior remain compatible.

Q: What are the key differences between these two devices?

A: The electrical specifications are equivalent across all critical parameters. The measurable difference is the forward voltage: PS9552L3-V-E3-AX specifies 1.65V typical, while HCNW3120-500E specifies 1.6V typical. This 50mV variation falls within normal component tolerance and does not affect circuit operation.

Q: Are there compliance or certification differences?

A: Both devices hold CSA and UL certifications. The HCNW3120-500E carries ROHS3 compliance; regulatory status for the obsolete PS9552L3-V-E3-AX is not specified in available data.

Q: Why is package format important in substitution?

A: The 8-SMD versus 8-DIP Gull Wing distinction affects physical mounting methodology. SMD (Surface Mount Device) packages use adhesive and reflow soldering, while DIP (Dual In-line Package) formats may use different assembly equipment and wave soldering techniques. PCB footprint compatibility must be confirmed before component substitution.

Q: What inventory status should influence my sourcing decision?

A: The PS9552L3-V-E3-AX is discontinued (663 Pcs listed as legacy stock). The HCNW3120-500E is Active production with 20400 Pcs available. For new designs or ongoing production requirements, the Broadcom device provides assured supply continuity.
